| dc.description.abstract | Investigation on "Effect of entomopathogenic fungi on sucking pests and leaf feeders of vegetables under in vitro conditions" was carried out II1 the Insect Pathology Laboratory, Department of Agricultural Entomology. College of Agriculture, Vellayani. Among the seven entomopathogenic fungi tested, Be auver ia r a l it ura and Peri call ia ricini, an aphid isolate of Fusarium pallidoroseum infected aphids Aphis craccivora and Myzus pers icae while Rhizop us oryzae caused mortality of Dysdercus cingula/us. The LCso values for B. bassiana were calculated as S.75 x 108. 6.99 X J08 and 2.72 x 105 spores m]"1 against S. derogat a. S. l it ura and P. rici ni respectively. F. pallidoroseum caused SO per cent mortality of A. cracci vora and M. persicae at 3.86 x 106 and 0.72 x 106 spores 111]"1 respectively. R. oryz ae caused 50 per cent mortality of D. cingula/us at 4.15 x 106 spores mrl. Evaluation of different naturally available substrates for mass multiplication of B. bassiana. F. p all i dor o se um and R. oryz ae revealed that both rice bran and gingelly oil cake were suitable for the mass multiplication of these fungi.'Among the liquid substrates. coconut water produced maximum mycelial growth of all the fungi. At room temperature. B. bassiana retained the vi.ulerice up to five months after inoculation in rice bran and gingelly oil cake. hut the vi rulence of the fungus was drastically reduced after two months or storage. F. p al lidorosetnn retained the virulence upto six months in rice bran and gingelly oil cake but R. oryzae lost the virulence after two months of storage. Coconut water and starch solution could not retain the \ i a h i lit y all d vir u I e n c e 0 f the fu n g i a ft e r t w 0 III 0 nth s 0 f s tor age. l-, p allidoroseum and R. OITZ(/(! with different pesticides revealed that two per cent neem oil emulsion could be incorporated with B. bassiana and R. oryzae without any inhibitory effect while sporultio n of F. pallidoroseum was inhibited by nee m oil. Mancozeb, dimethoate malathion, quinalphos and chlorpyriphos greatly inhibited the growth and sporulation of the three fungi tested. | en_US |
